Frequency vs Volume: What Really Builds a Lagging Muscle | J3U Podcast Ep. 245

Adding more sets to the same session is why your weak body part still will not grow. In this episode, we break down how to actually bring up a lagging muscle: picking the machine that fits your body instead of the lift you are attached to, training the weak part first in the session, and using frequency as the tool that lets you carry more quality volume. If you're serious about fixing a weak body part, this will change how you decide between adding another set and splitting that volume across another session. 🎓 Free Level 1 Masterclass John and Luke are hosting a free live Level 1 Masterclass on how we turn the research into real training decisions.
